Proc. ASME. ISPS2021, ASME 2021 30th Conference on Information Storage and Processing Systems, V001T05A004, June 2–3, 2021
Publisher: American Society of Mechanical Engineers
Paper No: ISPS2021-66171
... Abstract The migration from perpendicular magnetic recording (PMR) to heat-assisted magnetic recording (HAMR) in the hard disc drive (HDD) industry brings unique challenges for head-disc contact detection (CD) and with precisely setting head-disc clearance. In this study we provide numerical...

Proc. ASME. ISPS2020, ASME 2020 29th Conference on Information Storage and Processing Systems, V001T05A005, June 24–25, 2020
Publisher: American Society of Mechanical Engineers
Paper No: ISPS2020-1958
... Abstract As the Hard Disk Drive industry migrates from PMR to HAMR technology, it is important to understand differences in the measurement of contact detection between PMR vs. HAMR media. Compared to PMR media, HAMR media tends to be rougher and has a higher thermal conductance. Since some...

Proc. ASME. ISPS2019, ASME 2019 28th Conference on Information Storage and Processing Systems, V001T03A002, June 27–28, 2019
Publisher: American Society of Mechanical Engineers
Paper No: ISPS2019-7443
..., USA ABSTRACT The key features for Heat Assisted Magnetic Recording (HAMR) head-disk interface (HDI) are higher temperature, rougher media grains and harder disk properties. As a result of these features, it is critical for HDI especially the head to remain wear resistance, contamination robustness...
